Simplify the following expression: 8x − 8y + 5z − 3x − 14y + 3z a. 11x − 22y + 8z b. 5x − 6y + 8z c. 5x − 22y + 8z d. 11x − 6y + 8z

Step-by-step explanation:

Given : 8x−8y+5z−3x−14y+3z

To find : which of the following is the answer

a. 11x − 22y + 8z  

b. 5x − 6y + 8z  

c. 5x − 22y + 8z  

d. 11x − 6y + 8z

Solution :

Thus the simplified expression is

Thus option C is correct .

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
